1) yes. it’s lgbtqiA+
2) im not an expert on language or anything, but to me “cishet” means someone who is cisgender, heterosexual, heteroromantic and not-intersex (i think the word for that is perisex?) so a “cishet aro/ace” is a bit of a contradiction
3) i will accept exactly zero (0) discourse on this blog. including people asking me to justify this. there are tons of great blogs which will do a much better job than me at explaining this, go ask them
Fuck JKR
